Okay, I figured it out.  Gee, seems that if you read the documentation and
source code VERY CLOSELY and repeat it to yourself over and over something will
eventually start making more sense.
 
To pass along the two Major Things I discovered:
 
1) #_AESuspendTheCurrentEvent must occur inside the handler called by the
operating system, which is most definitely *not* the handlers defined by defun
or defmethod.  This call needs to come from within #defer-appleevent-handler,
which is a defpascal in the source code.
 
2) Don't try testing this feature by writing both the send and receive Apple
Events inside the same MCL 'cause it won't work.  I finally noticed -- after
staring at #'defer-appleevent-handler for two hours -- that some code in there
forces the event to be handled right away (to keep events from falling all over
each other).
 
I did finally get it all working to my satisfaction, if anyone wants more gory
details.
